[GRASS-user] v.buffer: circles around points

Hi,

I'm starting to use v.buffer to create circles around points on
Lat/Long vector maps.

When entering a value for the distance parameter for v.buffer to
create circles for points on lat/long maps, is the distance entered
the radius of the circle or is it the diameter? or some other
variable?

Thanks in advance,

Sharon

Hi Sharon,

that sould be the radius, but:

due to changing distances on latitude, the circle is not a true circle, as you can see when you reproject the map.

The buffer distance is in degree.

Hope, everything is correct,
regards,
Achim
